Tesla won't say so itself, but its much-discussed mainstream electric Model 3 appears to be powered by a battery about 11% smaller than the tiniest offered for its showcase luxury Model S, according to researchers who have gone to work figuring it out.

Vital news for battery fanatics: At a time researchers around the world are attempting to discover a breakthrough super-battery to bring electric cars to the masses, there is unusual interest in every detail about the $35,000 Model 3, which was launched July 28.

It's not clear why Tesla and CEO Elon Musk have been all-but silent about the battery, the car's most important spec, given that they have released at least bare-bones detail as a matter of course about its other vehicles. Tesla did not respond to emails from Axios about the battery.
